I use libre office, OP. It's a free download, and it is 99.8% compatible with all Microsoft Office products (it has a few technical features that MS lack, and some of the more advanced formatting on the database and spreadsheet options are a little different).
You can open your doc and print it out flawlessly with libre office. The address for it is
Home | LibreOffice - Free Office Suite - Fun Project - Fantastic People .
Locate the file you need printed. Then open libre office after installing it, and "open file." It'll pop up your file window and you can click til you get to the exact file, or type in the exact name with the windows built-in search engine.
Then select print, and print it out.
To hook up your printer, it'll depend on the printer. If it's a newer model wifi-capable HP all in one, just connect it to the computer or directly to the modem, and the LED screen on the printer itself should walk you through the process. Takes around 4 minutes if you know what you're doing, maybe 15 minutes if you're fresh from the turnip farm
